The specific embodiment
Referring to Fig. 2-4, the utility model embodiment provides a kind of locking device, comprises lock composition 1 and latch hook 3.Wherein, latch hook 3 is welded on bottom door 2.Latch hook 3 front portions are provided with guiding surface 9 and the second fillet 10, and middle part is provided with arc-shaped depression portion 7 and the first fillet 8.Lock composition 1 comprises rotating mechanism, lock 16 and spring 17.Lock 16 front part sides walls offer oblong pin hole, are welded on car body 4.Spring 17 one end carrying wheel words, the base plate of other end carrying lock 16.Wheel word comprises roller 11, roller mount 15, round pin 12 and spring cotter 14.Round pin 12 is successively through pin hole, roller mount 15 and roller 11.Roller 11 and latch hook 3 interlocks, can rotate by counter roller seat 15.Round pin 12 is locked by spring cotter 14.Roller mount 15 be shaped as U-shaped, be arranged on lock 16 inside.The bottom support of roller mount 15 is on spring 17.The utility model locking device also comprises packing ring 13.Packing ring 13 is arranged between spring cotter 14 and lock 16, for reducing the friction of spring cotter 14 and lock 16.
The utility model provides a kind of embodiment, and referring to Fig. 7, in the time that bottom door 2 tops have living space, latch hook 3 is arranged on the top of base.The distance of latch hook 3 installation sites and bottom door 2 centre of grations is less than the distance of bottom door 2 bearing load point of actions and bottom door 2 centre of grations, and the pulling force that latch hook 3 bears is greater than bottom door 2 bearing loads.The load of bearing when bottom door 2 is less, and when larger switching power can be provided, latch hook 3 is arranged on to the top of base 2.
The utility model also provides a kind of embodiment, and referring to Fig. 8, in the time that bottom door 2 bottoms have living space, latch hook 3 is arranged on the bottom of base.The distance of latch hook 3 installation sites and bottom door 2 centre of grations is greater than the distance of bottom door 2 bearing load point of actions and bottom door centre of gration, and the pulling force that latch hook bears is greater than bottom door bearing load.The load of bearing when bottom door is larger, need to reduce as far as possible bottom door opening and closing power time, latch hook 3 is arranged on to the bottom of base 2.
In the time that bottom door 2 is closed, latch hook 2 is with bottom door 2 motions.When latch hook 3 is during near roller 11, under the power of the closing effect of bottom door 2, latch hook 3 relies on the second anterior fillet 10 to drive roller 11 along lock 16 longitudinal movements with guiding surface 9, and the second fillet 10 is convenient to latch hook 3 and is moved on roller 11.By roller mount 15 Compress Springs 17, and travel forward along guiding surface 9.In the time that bottom door 2 is closed completely, the arc-shaped depression portion of latch hook 37 falls to closing with roller 11 cylindricals completely hooks.
Referring to Fig. 2, when bottom door 2 is during in closed condition, spring 17 is in compressive state, and spring 17 produces all the time a bounce and acts on latch hook 3 by roller mount 15, round pin 12.Latch hook 3 is held on roller 11 under spring 17 counter-force effects.In the time that bottom door 2 one-level lockings lost efficacy, because latch hook 3 and roller 11 are mutually stung tightly and hooked, the load that latch hook 3 bears bottom door and vibratory force are delivered on car body 4 by roller 11, round pin 12, lock 16, stop bottom door 2 to rotate, thereby realize bottom door 2 secondary self-lockings.
Referring to Fig. 5-6, in the time that bottom door 2 is opened, latch hook 3 is with bottom door 2 motions.Under bottom door 2 crack force effects, latch hook 3 is relying on arc-shaped depression portion 7 and the first fillet 8 to drive roller 11 along lock 16 longitudinal movements, and the first fillet 8 is convenient to latch hook 2 and is departed from roller 11.By round pin 12 and roller mount 15 Compress Springs, and travel forward along arc-shaped depression portion 7, latch hook 3 progressively departs from roller, and bottom door 2 relies on cargo weight and deadweight to open completely.
The lock composition of the locking device that the utility model provides is fixed on car body, latch hook is fixed on bottom door, in the time that bottom door one-level locking lost efficacy, by latch hook and roller interlock, bottom door deadweight and cargo weight and the vibration of bearing are delivered on car body, stop bottom door to rotate, realize the locking of bottom door, thereby improve the reliability of vehicle bottom door locking, effectively preventing that vehicle is in operation occurs, because bottom door is from the serious accident such as open the derailing that self-unloading causes and tumble, to guarantee the locking device of vehicle operating and personal security.
It should be noted last that, the above specific embodiment is only unrestricted in order to the technical solution of the utility model to be described, although the utility model is had been described in detail with reference to example, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
